When as7 has no metrics yet calculated, it used to return "No metrics available".
The as7 plugin reacts on this string.
AS7 has changed the code and now sends JBAS018003: No metrics available
This results in tons of error messages like this in the agent log:
2012-05-14 11:41:45,281 WARN [ResourceContainer.invoker.daemon-32] (rhq.modules.plugins.jbossas7.WebConnectorComponent)- Non numeric input for [errorCount] : [JBAS018003: No metrics available]
